On a day to day basis, the most common thing which system administrators do is to check on every storage array is its system health, to determine whether the array is in good shape or working with a partially failed or fully failed component.
Most of the storage system administrators face issues with such task as they have to depend lot many software to get a clear idea of what is happening with the system,
In this article we will explore the possibilities of checking 3PAR StoreServ system health using native commands and its different options.
We use 2 commands quite often to determine the health of the system and they are checkhealth and showalert
While checkhealth command checks the status of different hardware components and reports the status, showalert displays system alerts.
showalert when used with no options, only new alerts will be displayed. -all will display all alerts irrespective of the the category whether it is service alert or general notification
checkhealth when used with no options, a thorough check(-svc) is performed. The most common options used along with checkhealth are as follows,
–detail :Will display detailed information regarding the status of the system.
-full :Will perform the maximum health check.
Once check is completed, it will show you the current status and its description.
Note:- You can also prepare a schedule to check the system health status and configure them for email forwarding so that you don't have to login to each array to see what is happening.
